Swiss appliance manufacturer Koenig makes this HeatsBox, a lunch box that "exactly meets the needs of the Swiss population in terms of hot meals," the company writes. The container features an all-around heating element, "for an even heating process that retains the fresh taste and full nutritional value of the food."
You can set the unit to toasting, gentle heating or fast heating, and the temperature is adjustable from 50° C to 85° C (122° to 176° Fahrenheit). It can also be set to heat on a timer. (Sadly, the interface appears to be via app.)
The stainless steel inner container is easy to clean, and "The lid is absolutely tight, even soups can be transported."
The 1kg (2.2-pound) unit plugs into a wall socket and can also be plugged into a 12V car outlet (with a non-included adapter).
